Diagnostics for I/O remove locks

NTDEV
1

Clearly the Microsoft implementation of I/O remove locks keep track of each
acquire/release on debug builds. How do I enable / control / view this
information?

Is there a KD extension for dumping this? I’ve searched the interwebotron,
OSR list archives, MSDN, etc. all to no avail.

I’ve faced this in the past and =>

  1. I was told that there is no way to control this debug specific
    behavior. You can’t turn it off (or on :-))

  2. MS will improve their docs about the debug specific behavior of IO
    remove locks.

  3. If you use a separate tag to initialize the remove lock, then you can
    at least track it’s mem usage via utilities like pooltag

!remlock [1]

You can specify the 1 if your driver is built CHK,otherwise the extra storage required for the lock tracking information is not present.
